1. The management of the cornices in various fields is timely, and the growth conditions of the same crops are different. Therefore, according to the actual situation of the insect case report combined with Honda, the time of application of the drug should be applied at the right time. Both advance and push will not pay off. For example, rice aphids must be used at the peak of their incubation, and the effect is best.
2. Alternate use of the same pests, the use of different varieties of drugs with the same efficacy of alternate rotation spray, can overcome the resistance of insect pests and achieve good control effects. For example, aphids and spider mites can be used alternately with urinary washing agents, chlorpyrifos, chlorpyrifos, methamidophos, and phoxim.
3. Mixed spraying sometimes can occur several crop pests and diseases at the same time. In order to achieve the purpose of concurrent treatment, one or two kinds of pesticides for controlling pests and diseases can be scientifically selected for use with the mixture, so as to achieve the control effect of "one arrow and two sculptures".
4. The points of cultivation of crops and fruit trees are different. If they are treated equally, the effect is not good. Plants with serious pests can be selected and directly smeared with a brush. This method has special effects on red spiders and beetles on cotton, vegetables and citrus.
5. Any kind of pests and diseases have their symbiotic laws. It is necessary to choose the right pesticides and the best prevention time, and thoroughly and thoroughly kill and prevent them in time.
6. The combination of a single drug and a broad-spectrum, low-toxic, high-efficiency, and low-residue pesticide can treat multiple pests and diseases. For example, organophosphorus pesticides have special effects on insect pests such as red bollworm, aphids, thrips, and planthoppers. Once these kinds of pests occur, they can be treated with one spray.
